Abstract

An intensive study was undertaken to investigate the influence of bioagents population under different weather parameters in rice field ecosystem of Eastern Uttar Pradesh conditions for two consecutive years, 2014 and 2015. The population of bioagents were observed under particular weather parameters, i.e., temperature maximum, temperature minimum, relative humidity, and rainfall in different growth stages of rice. The influence of weather parameters on population of bioagents were inferenced by correlation coefficient. Of the total observed population of most bioagent groups in all growth stages of rice under temperature maximum, temperature minimum, relative humidity, and rainfall, the correlation coefficients were - 0.602, - 0.581, - 0.490, and 0.768 for predators; - 0.459, - 0.436, - 0.337, and 0.649 for parasitoids respectively. The abundance of most bioagent groups, both predators and parasitoids were inferenced negative correlation with particular weather parameters, except rain

Conclusion

Both most bioagent groups (predators and parasitoids) and major bioagent species were highly decreased with increasing temperature maximum, temperature minimum, and relative humidity and decreasing rainfall in seedling stage, and highly increased with moderately decreasing temperature maximum, temperature minimum, and relative humidity and increasing rainfall in transplanting stage, while moderately decreased with decreasing temperature maximum, temperature minimum, and relative humidity and increasing rainfall in flowering stage respectively.
